You may not notice these changes and I only mention it to give you an indication of the characteristics of Teflon. During the break-in cycle of these capacitors, they will go through different stages.
One you reach the 400 hour mark (16 days), you are starting to reach sonic nirvana and it will not be long before you are experiencing the truest potential of Teflon capacitors. It's been a long road but you will probably find the journey well worth it. This is the point where the midrange magic is apparent. You should notice a sense of texture and realism that is uncanny. The bass is quick and firm and the highs extended with a great sense of air. You will now start realizing a wide, spacious presentation as well. At this point, I don't receive any phone calls at all as you will be too involved in your music to want to waste time talking to me...>>"
..back on an old issues which refers to the 0,22 V-Cap CuTF capacitor:
I want to confirm what is write here and to draw attention about CuTF burning-in (I am referring on especially to the 0,22uF capacitance). This capacitor is burning-in extremely hard on this position!! Considering that, I perceive increasingly better what is narrated here about sound effects: the bass is quick and firm, the midrange are coherent and reliable; the highs extended with a great sense of air; a wide, spacious prezentation as well. And last but not least, is apparent a clear improvement in the texture (realistically).
Ok. I estimate that CuTF have about 900 hours of burning-in... In the range which is marked with four houndred >> eight/nine houndred hours, their sound is changing a lot from one week to another, and only gradually you realize what they prepare. I would say it is extremely annoying to listen to in the meantime. These capacitors are for those who want to exercise the patience!
